SHELVING.

SPECIFICATION forming part of Letters Patent No. 641,212, dated January9, 1900.

Application filed January 12, 1899. Serial No. 701,919. (No model.)

To all whom it may concern:

Be it known that I, J AMES M. LIPPINoorT, residing at Oakland,in thecounty of Goles and State of Illinois, have made certain new and usefulImprovements in Shelving, of which the following is a specification.

My invention is an improvement in shelving, and particularly in thatclass of such apparatus in which a shelving-section is movablevertically to a height above the ordinary fixed shelving and then isadjusted laterally back above said fixed shelving, thus utilizing thespace above the fixed shelving and permitting the movableshelving-section to be conveniently brought within reach.

The invention consists in certain novel constructions and combinationsof parts, as will be hereinafter described, and pointed out in theclaims.

In the drawings, Figure 1 is a vertical longitudinal section of myapparatus, the shelving-section being lowered. Fig. 2 is a detailsection of the upper portion of the apparatus, showing theshelving-section adjusted back in the lateral guideway. Fig. 3 is adetail perspective view illustrating the cord or line for advancing theshelving-section, the guide forsaid cord,and the means whereby the sameis detachably connected with the shelvingsection. Fig. 4 is a detailview illustrating the drums for operating the hoisting and laterally-adjusting lines of the shelving-section and the levers for operating saiddrums. Fig. 5 is a vertical section of an apparatus, illustrating, inconnection with a cord for lifting the outer edge of theshelving-section, the special means for guiding and detachablyconnecting the line with such section, which is shown in Figs. 1, 2, and3, for advancing said shelving-section in its lateral guideway; andFigs. 6, 7, S, and 9 are detail views of the construction shown in Fig.5.

The shelving-section A is movable vertically in the guideways B andlaterally in the guideways C, the latter extending rearwardly from andcommunicating with the upper end of the guideways B, as shown in Fig. 2.The shelving-section is lifted and moved backward in the guideways B andG by the cord or line D, which is connected with the shelving-section,passes upward over the guidepulley D and thence downward, and is securedto its drum D which will be more fully described hereinafter.

The cord or line E, which in the construction shown in Figs. 1, 2, and 3is used for adj ustin g the shelving-section forward preparatory tolowering the same, is secured to the drum E passes thence up over theguidepulley E, thence forward over the pulley E and thence back throughthe guide E and the line E is provided with a head E which is too largeto pass through the guide E so that it will be stopped by such guide inthe position shown in Fig. 1. Upon the shelving-section A, I provide acatch A, as best shown in Fig. 3, which when the shelving-section Aapproaches its uppermost position engages the head E on the line E andduring the backward movement of said shelving-section draws such headand the cord to which it is attached rearwardly to the position shown inFig. 2. Now by drawing on the cord E when the parts are as shown in Fig.2 the head E pressing against the catch A, will draw the shelvingsectionforward until the latter is in position to descend the guideways B, andas the shelving-section descends the catch A will slip out of engagementwith the head E and the latter will rest against the end of the guide Ein the position shown in Fig. 1, so that it can be rengaged by the catchA when the shelving-section is again moved upward.

The drums E and D are loose upon the drive-shaft F and may be clutchedtherewith by moving them endwise against their respective shoulders cand d the latter being fixed to the shaft F and such shaft being drivenby any suitable power. It may be steam, compressed air, electricity, orany other or" the well-known forces.

In operating the drums D and E into engagement with their respectiveshoulders I employ two levers G and H, the former being pivoted at Gbetween its ends and having one end G arranged to press against one endof the drum D and force such drum to bear at its other end against theabutment 01 The second lever H is pivoted at G between its ends and isarranged at one end H to bear against one end of the drum E to forcesuch drum into engagement with its shoulder Q The other end of the leverH is connected by a rod H with ahand-lever H adjacent to the handle ofthe lever G. By this construction the lever G can be operated to pressthe drum D into engagement with the shoulder 01 so that the drum will beoperated to wind up its cord D, and thus lift the shelving-section andretract the same to the position shown in Fig. 2. The lever G may bethen adjusted clear of the drum D and when it is desired to lower theshelving-section the lever H may be moved to press the drum E intoengagement with its shoulder 6 which will draw upon the cord E and movethe shelving-section forward in position to descend the guideways B.WVhen the shelving-section has reached such position, the lever H may bereleased and the lever G be caused to operate the drum D sufficiently toprevent the shelving-section from descending too rapidly.

In the construction shown in Fig. 5 the frame has vertical and lateralguideways. A weight is employed to elevate the shelving section, theline connecting such weight with the shelving-section beingcarriedthrough a tubular guide and provided with a head arranged to be stoppedby said tubular guide and to be detachably engaged bya V-shaped catch onthe shelving-section. By the operation of this construction as theshelving-section moves forward to position to descend the verticalguideways or back out of such position the V-shaped catch moves into andout of engagement with the head on the line, so that as saidshelving-section is lowered it will draw the line down and will move outof engagement with such line as it (the said shelvingsection) moves backin its lateral guideways.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In an apparatus substantially as described, the combination of thevertically and laterally movable shelving-section, a cord or cablehaving a head, means on the shelvingsection for detachably engaging saidhead, and a guide for said cord or cable forming a stop for the headsubstantially as set forth.

2. In an apparatus substantially as described, the combination of theshelving-section, the framing having a guide for the cable or cord, thecable or cord passed through such guide and having a head arranged to bestopped by the guide, and a catch on the shelving-section for detachablyengaging said head substantially as set forth.

3. In an apparatus substantially as described, the combination of theshelving-section, a cord for operating the same, a guide for such cord,a head on the cord too large to pass through such guide, and a catch onthe shelving-section by which to engage said head and by pressurethereagainst to draw the cord through the guide substantially as setforth.

4. In an apparatus substantially as de scribed the combination of theframing having vertical and lateral guideways, the shelving-section,means for lifting said section and for adjusting the same rearwardly inthe lateral guideways, a cord for advancing the shelving section in thelateral guideways, means whereby to stop said advancing cord when theshelving-section is in its foremost position and adetachable connectionbetween said cord and the shelving-section substantially as set forth.

5. In an apparatus substantially as described, the combination of theframing having vertical and lateral ways for the shelvingsection, theshelving-section, the line or cord for elevating said section, aseparate line for moving said section forward in the lateral guideways,a drive-shaft, drums to which said lines or cords are connected andmeans whereby said drums may be clutched to the drive shaftsubstantially as set forth.

6. The herein-described improvement in shelving comprising the framehaving vertical and lateral guideways, the shelving-see tion movable insaid guideways, the driveshaft, the drums thereon and spaced apart, thelines for lifting and for advancing the shelving-section, such linesbeing connected with their respective drums, the pivoted lever arrangedto clutch one of the drums to the drive-shaft, and a second leverpivoted to said first lever and arranged to clutch the other drum to thedrive-shaft substantially as set forth.
